Principal AI Engineer

The role

You will design, develop, and optimize scalable AI systems for cybersecurity solutions. You will build AI layers for autonomous detection and mentor engineering teams.

What you will do

• Design and build the AI layer for autonomous detection, RAG-backed investigation, and auto-remediation workflows.
• Develop and productionize large-scale LLMs, graph-based reasoning engines, and streaming feature pipelines.
• Own evaluation and reliability including prompt libraries, fine tuning, red-team testing, latency budgets, and fallback strategies.
• Mentor and grow a cohort of AI engineers.
• Run design reviews and uphold code quality.
• Partner with Product, Detection Engineering, and Customer Success to translate attacker behavior into detections.
• Experiment with retrieval-augmented generation, tool-calling agents, and multi-modal models.

Required qualifications

• 10+ years of experience in software development, engineering production systems using modern programming languages (Python, Go, Rust, or Java).
• Deep knowledge of LLM architecture, prompt engineering, and Vector database workflows.
• Hands-on experience building agents, orchestration frameworks (LangChain/LangGraph, Agno AGI, or custom), and evaluation harnesses.
• Deep understanding of microservices architecture, containerization (Docker, Kubernetes), and event-driven systems.
• Strong fundamentals in API design (REST/gRPC) and distributed systems.
• Clear, concise communication skills and a bias for collaborative problem-solving.
• Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field.

Nice to have

• Prior work in cybersecurity (SIEM, EDR, SOAR, or MDR).
• Experience with graph databases or security-focused knowledge graphs.
• Familiarity with cloud infrastructure security (AWS, GCP, or Azure).
• Background leading teams in high-growth startups or enterprise SaaS.
• Relevant certifications (AWS/GCP Professional Engineer, Kubernetes, or security-related credentials).

Benefits

• Competitive salary and benefits package.
• Opportunity to work with cutting-edge AI-driven cybersecurity technologies and Google SecOps solutions.
• Collaborate with a talented and innovative team.
• A culture of growth and development.
